Product Details

For use with OEM Airbox or other intakes that use OE duct

    The ECS Tuning Kohlefaser Luft-Technik (Carbon Fiber Air Technology) Dual OE Inlet Duct Kit, is a premium in-house designed engine aspiration product that not only delivers remarkable power gains, but also blends automotive engineering into an artistic canvas of underhood beauty. The ECS Dual Inlet Duct replaces the undersized OEM air inlet duct in favor of a smoother flowing and larger capacity dual air inlet scoop designed to feed massive amounts of cold outside air directly into the air filter! 

The OEM inlet duct was tailored to the majority of everyday drivers who prefer a muffled, relaxed driving experience. This came at the cost for air induction capacity and design. The OEM inlet is restricted to available airflow from two tiny passages on the opposite of the airbox at the front and rear of the inlet duct. At higher speeds we found that the rear-facing inlet draws in hot, engine-bay air into the airbox, increasing airbox inlet temps. 

The OEM inlet duct has further issues for performance-minded owners, such as a blocked off inlet passage directly in front of the airbox along with abrupt edges leading into the air inlet channel. 

By replacing the OEM inlet duct with the ECS Carbon Fiber Dual Inlet, considerably more airflow is available to the air filter. Our design increases frontal cold air area by as much as +285.6% for a massive increase in cool, outside air! We also measured a reduction in airbox inlet temperature of -26° F at redline! 

Made from lightweight, hand laid carbon fiber, it perfectly contours to the front core support, supplying smooth airflow into the airbox inlet. The complete kit also includes a silicone coolant reroute hose for a sleek, attractive appearance. All needed hose clamps and stainless install hardware is included for a complete package to increase engine bay beauty and impressive performance!



  • The beautifully crafted inlet duct is manufactured from lightweight, hand-laid carbon fiber 2x2 twill weave. The final outer layer is gloss clear coated for UV and heat protection for continuous operating temperatures of up to 300° F. It's engineered for a perfect contour to the OEM core support and features a gradual taper to provide a smooth collection of cool outside air into the air filter.

  •  Improves on the OE design by providing DIRECT airflow into the air box and maximizes available area by utilizing both sides of the front grille assembly 

    • Stock Inlet Total Area (Hot & Cold Air) = 21.41in²

      • Stock Duct Frontal Inlet Area (Cold Air) - 11.98in²

      • Stock Duct Rear Inlet Area (Hot Air) - 9.43in²

    • ECS Inlet Area (Cold Air Only) = 34.22in²

      • Total area increase over OEM - +159.8%

      • Frontal area (Cold Air) increase over OEM - +285.6%

  • Compatible with OEM airbox or aftermarket intakes that utilize the OE air inlet scoop

    • The flanged mating surface seals within the OEM airbox just like the stock inlet duct

  • Includes coolant reroute house for a cleaner appearance

    • Includes hose clamps and integrated check valve for OEM-like operation 



  • The increase in available air inlet volume easily translates into more airflow available to the air filter. Whether your vehicle is equipped with the stock airbox and a high-flow filter or utilizing an aftermarket intake system with the OE inlet scoop, the ECS Dual Inlet outperforms the OEM inlet in all areas.

  • Not only does the ECS Inlet Duct feed a massive amount of greater airflow into the airbox from the frontal area but it eliminates the "hot air inlet" on the OEM inlet duct's engine bay inlet passage. Our Engineering team evaluated the performance of both products and found that with the OEM inlet duct, airbox temperatures increased dramatically at high RPM (~4,600 RPM+) due to airflow being pulled from the hot engine bay side. We measured up to 26° F. temperature decrease with the ECS Dual Inlet versus the OEM!



  • Our ECS Carbon Fiber Dual OE Inlet Duct Kit was designed, engineered, tested and quality inspected by our Research and Development team in our Wadsworth, Ohio facility. We ensured the highest level of precision and quality is delivered throughout rigorous long term product testing and leading edge product development methods.



  • Installation is straight-forward with basic hand tools. Simply remove the OEM inlet duct.

  • Once removed, remove and discard the OE coolant line the runs "over" the OEM inlet duct.

  • Install the ECS coolant reroute hose, this will go "under" the ECS inlet duct.

  • Install the ECS inlet duct with the newly included stainless steel hardware and enjoy more available airflow!
